How To Defeat Obama and Repeal His Socialist Programs – A Patriot's Guide identifies the vulnerable Senate Democrats and explains how to beat them:

The Vacancies

We need four seats to control the Senate and three likely pickups are Democratic retirements in red states: North Dakota, Virginia, and New Mexico. In Virginia, former Governor and Senator George Allen offers the best chance of victory. We also expect that Herman Kohl, Democrat of Wisconsin, may retire – if he knows what's good for him!

Ben Nelson, Nebraska

After his vote for Obamacare, we have waited for 2012 to come around so we could beat Ben Nelson! And it is not just Obamacare. Read how Nelson pushed an amendment that would have benefited one company: Warren Buffet's Berkshire Hathaway. And, by coincidence, he and his wife own between $1.5 million and $6 million in the company's stock, their largest investment!

We hope that Republican Governor Dave Heineman takes him on. Rasmussen shows him ahead of Nelson by 61-30!
